Let's compare-

Bhopal: 2000-8000 estimated deaths within 2 weeks of disaster

2023 Ohio train derailment: 0 estimated deaths within 10 days of disaster

I definitely see why it's appealing to exaggerate something that has been under-reported, and it's popular to do, but I don't think it's a winning strategy.

I think the max number of people will listen if the severity of events is portrayed in context. People mistrust the media for sensationalism and are looking for better ways to understand the world more accurately.
